"OK" Key - This key is used to complete entries on the keypad. This key is also used to acknowledge events. Acknowledging an event will remove the event from the display temporarily. Severe events cannot be acknowledged."Gauge Key" - The VIMS displays the checked parameters when the key is pressed. Depressing the arrow keys will scroll through the parameters. First enter the parameter number. Then press the "GAUGE" key in order to select a parameter."F1" Key - The "F1" key provides additional information about the event that is being displayed. The "MID-CID-FMI" is displayed for the maintenance events. The current parameter value is displayed for data events.Each service program code is a unique number of one to ten digits. The service program codes have an equivalent letter that describes the service operation. The letter equivalent allows an easier way to remember the service program code for the operation. The English letter equivalent for each service program code is shown in the parentheses. Different on board languages have no effect on the codes.After entering the service program code on the keypad, the service code must be completed by pressing the "OK" key within 5 seconds after entering the last SPC character.Note: For a full description of the VIMS, see Service Manual, RENR2630, "Vital Information Management System".Caterpillar Monitoring System

Diagnostic information concerning the transmission/chassis ECM is sent on the Cat Data Link to the Caterpillar Monitoring System. Service personnel must be familiar with the Caterpillar Monitoring System in order to troubleshoot the transmission/chassis ECM. For troubleshooting the Transmission/Chassis ECM, service personnel must place the Caterpillar Monitoring System in the Service Mode (mode Number 3). The service switches (service switch, clear switch, and calibrate switch) are used for changing the display modes of the monitor.Diagnostic Codes
The transmission/chassis ECM detects diagnostic codes that occur with most of the inputs and the outputs. A diagnostic code is detected when the signal at the connector contact of the ECM is outside a valid range. The ECM then records the diagnostic code. If the diagnostic code goes away, the information for the diagnostic code remains stored for future reference. If the Transmission/Chassis ECM detects a diagnostic code, the operator is informed. An indicator in the display area tells when a diagnostic code is currently present. When diagnostic code indicator (11) is showing "SERV CODE", a diagnostic code is currently present. When "SERV CODE" is OFF, a diagnostic code is not currently present. Diagnostic code indicator (11) works in the
